- UNITED STATES PATENT oFFIcE.

To all 'whom it may concern.' f f l Be it known that I, ALEERTR.v YA'rr, a citizen of the United States, residing at Olds, in the county of' Henry and State of Iowa, have invented Vnew and useful YImy 'provements in Couches, of which the folcouch; Fig. 5 is 4a broken end of the couch.

owing is a specification.

The present invention relates to improvements 1n that, class of couches which can be tilted by the occupant ,to any desired angle; and which are especially useful in the treatment of certain abdominal ailments.y The` invention is an improvement upon the couch for which Letters Patent N o.' 1,099,092 were granted to me 4J une 2nd, 1914. The object of the vinvention is to provide a couch the form of which can be changed in lseveral different ways, to greatly simplify the construction\thereof, and to render it easier'of manipulation.

In the accompanying drawing, Figure 1 is a side view of thecouch in a horizontal position, showing also in dotted lines the head rest elevated; Fig. 2 is a similar view showing also the back rest elevated and the "-body of the couch also slightly elevated in the opposite direction; Fig. 3 is a longitudinal sectional view showing ythe couch greatly elevated at the foot; Fig. 4 is a broken bottom' plan view of one side of the plan view of an Referring to the drawing, 1 indicates a suitable base adapted to rest upon the door and upon which side pieces 2 lare secured yby screws `3. Secured to said side pieces is a shaft 4 upon which are rotatable pairs of l v bearing plates 5, dependin from plates 6 1 secured to the under side o thelower body section 7 of a couch. Connectingne `pair of said bearing plates are plates 8 through which extends a longitudinal shaft 9 lcarrying, between said plates 8, a worm 10, which meshes with a worm ysegment 11, fixedly secured, as shown at 12, upon the adjacent -side piece 2. Said shaft also passes through a bracket 13, and there is secured on the vso end of said shaft projecting through said bracket a miter gear 14 meshing Vwithr a miter gear 16, on a transverse shaft 17, having one bearing inthe end o f abent portion v18 of said bracket and passing through the vertical member of an angle iron 19 formingl part of the lower couch section. To the p end of said shaft so projecting through said vertical member is secured a toothed wheel is pivoted,

,head rest may be supported in a *l 20 and on the endof said shaft 1s looselymounted a lever 21 having a handley 22 extending over the edge lof the oo uch. To' saidr lever-21 isf pivoted at its mlddle a double-actin 'pawl 23 'so that it canengage thel toothe wheel in either direction o movement of the lever.

The occupant of thecouch can raise or lower the couch from an elevated position by (auslngone pointor the other of the paw movingthe lever in the proper direction.

By reason of the engagement of the worm wheell with the worm segment being nonreversible, the couch will'always remain in any position to which it has been elevated without the need -of any additional means for holdin it in said position.

To the oot'portion `of the couch body is secured an upper body section 24, to which as shown at 25, an upper back section 26, to'the vfree end of which is ivoted, as shownat 27, ahead rest 28. aid aised positlon, asshown in dotted lines in Fig. 1, by means of a rod 29, normally contained by frictional contact in a recess 30 in the head rest, of which one end is pivoted to the under side of the head rest and the other end can engage anyone of a series of sockets 31 1n a lon tudinal socket piece 32 in a recess in the ody.

to engage the toothed wheel and g In the same manner the back rest and i head rest can be supported in a raised 0- .sition, as shown in Fig. 2, by means o? a Vs1m1lar rod 33 pivoted to the back rest, the

free end of. which can engage any one of a series of sockets in a socket piece 34y in the couch body.

With certain abdominal and other troubles it is desirable that the patient should rest with his feet greatly elevated, and for this purpose there are provided ,clamps 36 secured t9 the foot of the couch, upon which are secured, by thumb screws 37, straps 38 by which the body of the patient can be suspended.

A roll or pillow 39 many be secured adjustably for tall or short persons, as may be required, in an one Iof a longitudinal series of ositions y means of pins 41 delos I pending rom terminal portions of the roll in Fig. 1, or tilted slightly,

It will thus be seen that the couch may be used in a reat if'ariety of positions, either straight an entirely` horizontal, as shown or greatly tilted, as shown in F igy', or with the head rest tilted, asshownjin dotted lines in Fig. 1,' or with the back rest also tilted, and in both of these latter positions with the lower portion of the couch either horizontal or raised, the latter position being shownin Fig. 2.

Means for enabling an occupant of a couch to vary its inclination comprising an upright, on which the couch is pivotally supported, a fixed worm-segment around its pivotal axis as center, a longitudinally extending shaft carried by ther couch body, a worm on said shaft iengaging said segment, an arm pivoted aboutr a transverse axis below the couch and extending labove the couch into a position convenient to be my hand lin the presence of two subscribing wltnesses.` l y I ALBERT R. HYATT.
